What happened
Wu Xinbo, dean of Fudan University’s Institute of International Studies, framed a simple causal path: when U.S. policy shifts toward transactional, America-first priorities, other states — especially China — gain diplomatic and strategic room to act. In the interview he links observable U.S. moves (less emphasis on alliance burden-sharing, more bilateral transactional deals, and clearer prioritization of domestic interests) to a set of reactions in Beijing that are already reshaping regional alignments and global narratives.
Wu’s diagnosis is less about intentions and more about incentives: when the United States signals reduced appetite for long-term, multilateral engagement, it changes how allies and competitors allocate resources and risks.
Who gains leverage
The immediate beneficiary is the Chinese state. Beijing gains leverage where U.S. commitments look contingent: in trade negotiations, regional infrastructure and development financing, and diplomatic forums where the presence or absence of a firm U.S. position alters coalition-building. Secondary gainers are regional governments and corporations that can extract better terms from a more transactional U.S. or pivot toward China’s offerings.
What mechanism is operating
The dominant mechanism is a reallocation of relative power through signaling and substitution. U.S. retrenchment is a public signal that reduces the credibility of long-term commitments. Other actors respond by substituting partners, investing in alternative institutions, and hedging. That substitution is practical (contracts, loans, military posture) and reputational (shifting norms and narratives about who provides stability).
Why it matters
These shifts change where influence is exercised and who sets rules. For the public, the consequence shows up in trade terms, supply-chain decisions, neighborhood security arrangements, and the cost of living through altered markets. The structural risk is that short-term transactional gains for one government produce longer-term strategic dependencies and fewer multilateral tools to manage transnational problems.
What to watch next
Watch U.S. alliance signaling (defense postures, joint exercises, trade commitments), Chinese offers (infrastructure financing, trade deals, investment patterns), and where smaller states place their bets. Tactical episodes — a new bilateral trade deal, a regional security pact, or a high-profile infrastructure agreement — will reveal whether substitution becomes durable power shift or a temporary rebalancing.
